The Healing Walk started in 2010 in Fort McMurray Alberta, which is located in the Northern Boreal Forest. Fort McMurray is in Treaty 8 where for the past 50 years there has been oil extraction. Initially the extraction was oil, it is now crude which is a much heavier form of oil and takes more energy and water to extract, making it one if the dirtiest oils on the planet.
The closest major river that runs through Fort McMurray is the Athabasca River. The Athabasca River starts in Jasper and runs through communities such as Fort McKay, Fort Chipewyan and Fort Smith and eventually drains into the Artic Basin. It virtually affects Treaty 7, 6, 8 and 11 directly.
